Figure 9 is a view, partly in' section and partly in elevation, of aplurality of the valve constructions of this invention mounted inatubing string with: a well packer.

In the drawings, the numeral 10 designates a valve 4 housing which is.tubular and which is connected at its upper end to a. well pipe ortubing 11 which extends to the surface of the well. Thelower end ofthevalve housing 10 is connected to an adapter 12, which in turn, isconnected to a lower section of well. pipe 1'4, or, if desired, to a.valve housing identical with or similar to the housing. 10. Thus, thevalve housing 10 is positioned, in the well pipe or tubing stringwhichextends from the surface of the well and it actually; forms a-. partthereof, with the bore 10a of the housing 10 being of substantially thesame diameteras the bore of the well pipe or tubing string. Within thevalve housing 10, there is mounted a valve or valve member 15 which isadapted to. be turned. or rotatedrelative to the housing 10 and. whichisformed with a bore 15a therethrough, which is slightly smaller indiameter than the bore. 10:: of. the housing. 10,,but which is also-ofsubstantially the same diameter as the diameter of the bore of thetubing string.

To provide fluid. communication. between the exterior of the valvehousing 10 and the bore 15a of, the valve member 15; one or more lateralports 20; are provided in the valve housing 10, which: are adapted to bemoved into and out of alignment with one or more ports. 21- in the valveor valve member 15, whereby the valve is either opened or closed,respectively. For turning the valve or valve element 15 to open or closesame, an actuating or jarring means A (Figure l) is provided which issuspended on a cable, wire line, or other similar flexible line P (Fig.1A) which extends: to the surface of.- the well, whereby the actuatingor jarring means or tool A may be lowered and raised thereon andalsomanipu-- lated thereby. As will be explained, the actuating tool. Ais so constructed that it can be lowered into'the wellpipe or'tubingstring 11', connected to the valve or valve element; 15,.then actuatedby a manipulation. of its flexible support line to impart a rotarymotion to the valve member 15 to turn same for actuating the valve, and

thereafter the actuating member A can be retracted from.

the well pipe or tubing string 11 for subsequent well operations whereinwell tools are passed through the bore 151: of the valve element 15, ifdesired.

Considering the details of the valve construction of this invention, thevalve elementor member 15 has a near the lower end thereof andv adjacentthe flow portsv 20'. The lower end of the valve member 15 has aplurality of cams or cam lugs 25 formed thereon, each of which restsupon and is adapted to slide relative to a cam ring 26 which rests uponthe upper end 12a of the tubular adapter 12. The upper end of the camring 26 is formed with a cam surface which has diametrically opposedhigh points or portions 26a and diametrically opposed low points orportions 26b, which are positioned between the high points 26a, wherebyas the valve member 15 is moved from its open position (Figure 2) to itsclosed position (Figure 1), the cam lugs 25 ride from the low points 26bof the cam ring 26 toward the high points 26a, so that the valve member15 is moved slightly longitudinally upwardly to tightly wedge thesurface 15b of the valve member 15 into contact with the tapered surfaceThus, a tight seal is formed between such metal surfaces 1% and b whenthe valve member 15 is in the closed position, because, as can be seenin Figure 1, the valve member 15 is raised with respect to the housing10 when it is in the closed position.

The cam ring 26 is prevented from rotating relative to the valve housing10 by reason of a key 27, which is mounted on the ring 26 and extendsoutwardly therefrom into a keyway 28, which is a longitudinal slot orgroove formed in the bore 10:: of the valve housing 10 at its lower end.To prevent fluid leakage between the threaded connection of the adapter12 to the valve housing 10, an O-ring 30 formed of rubber or othersimilar elastic material is mounted between the lower endrof the valvehousing 10 and an annular radially extending shoulder 12b on the adapter12.

The valve member 15 has a pair of diametrically opposed longitudinalslots 15c (Figure 2) which have upwardly curved walls which convergeinto diametrically opposed pointed upper ends 15d. The valve member 15is also provided with a lateral slot 32, which extends in an arc ofsubstantially 90 degrees, but preferably slightly more than 90 degrees,and receives a stop pin 33 mounted on the valve housing 10 (Figure 3).The diameter of the pin 33 is less than the height of the lateral slot32 so as to permit the longitudinal movements of the valve member 15relative to the valve housing 10 by reason of t2h6e co-action betweenthe cam lugs 25 and the cam ring The actuating member or tool A, whichimparts the turn ng or rotational movement to the valve member 15,includes an outer sleeve 35 (Figure 1) which has its upper end connectedto a suitable support, such as a cable or flexible wire line (notshown). A rod 36 is positioned Within the sleeve 35 and the parts 35 and36 are longitudinally moveable relative to each other, with suchlongitudinal relative movement being controlled by the movement of a pin37 extending outwardly from the rod 36 into a shaped guide slot 38 inthe sleeve 35. The lower portion 38a of the slot 38 is vertical orsubstantially vertical and the slot 38 gradually increases ininclination as it progresses upwardly so that the upper portion 38b ofthe slot 38 is substantially lateral or horizontal. Such construction ofthe slot 38 results in the rotational movement of the sleeve 35 relativeto the rod 36 as the sleeve 35 is permitted to fall by gravity from anextended position to the fully telescoped position shown in Figure 1.Thus, the sleeve 35 would be in the fully extended positwo when the pin37 is at the lower end of the slot 38 and it is in the fully telescopedposition when the pin 37 is at or near the upper end of the slot 38. Itshould be noted that although the lower portion 38a of the slot 38 isillustrated as vertical, it is generally preferable to provide suchlower portion 38a with a slight incline from vertical so that there isno sharp change in the movement of the pin 37 in the slot 38 as thesleeve 35 is dropped.

The lower end of the rod 36 is threaded or otherwise suitably secured toa body 40, and such rod 36 is preferably prevented from rotatingrelative to the body 40 4 r by a retaining set screw 39 (Figure 2). Onthe upper end of the body 40, an anvil ring 41 is mounted which has oneor more substantially vertical or longitudinal surfaces 41a which areadapted to be contacted by substantially vertical or longitudinal hammersurfaces 35a formed on the lower end of the sleeve 35. The anvil 41 isretained in position on the body 40 since the anvil 41 is formed in theshape of a ring and the rod 36 extends through the bore thereof (Figure2). Also, a dovetail joint is provided between the anvil 41 and the body40 by means of the downwardly extending flared projections 41b which fitinto complementary recesses 40a.

At about the midportion of the body 40, a longitudinal opening 4% isprovided for the mounting of a pair of pivoted latching arms 42. Thearms 42 overlap each other in scissor fashion with a pivot pin 43extending through the overlapped portions of the latching arms 42. Thelower portions 42a of the latching arms 42 are urged laterally outwardlyby a coil spring or suitable resilient means 44 which is confinedbetween the latching arms 42. The upper portion 42b of each of thelatching arms 42 are actually retracting dogs which also extendoutwardly from the longitudinal opening 4%, and such dogs 42b also tendto move outwardly and away from each other by reason of the urging ofthe coil spring 44.

When the actuating tool A is initially lowered into the tubing string11, the latch arms 42 are held in a retracted position by means of aretaining or lock ring 50 which is connected to the upper end of aslideable shaft 51. The retaining ring 50 has a substantially circularcentral recess 504: into which fit projections 420 on the lower end ofeach of the latch arms 42. The retaining ring 50 and the slideable bar51 are maintained in their upper or locked position during the loweringof the actuating or jarring tool A into the tubing string by a shear pin52 which extends into an annular notch 53 formed in the slideable bar51. i

To shear the shear pin 52, a collar finder 55 is pivotally mounted onthe member Slat the pivot pin 56 and a spring 57 resiliently urges thefinder 55 outwardly through an opening 400 in the lower portion of thebody 40. The finder 55 is adapted to seat or catch on the annularshoulder of the adapter 12 upon an upward movement of the actuating toolA after such tool A has been lowered through the bore of the valvemember 15 and the adapter 12. A downward force is thus applied to theslideable member 51 to shear the pin 52, whereupon the coil spring 60which is confined between an annular guide 61 and a nut 62 on the member51 urges the slideable member 51 downwardly to retract the retainingring 50 from the projections 420. When the retaining or lock ring 50 isthus moved below the projections 42c, the spring 44 acts to urge thelatching arms 42 outwardly so that as the actuating or jarring tool A israised in the bore of the adapter 12 and the valve member 15, the latcharms 42 are urged outwardly into the longitudinal slots of the valvemember 15 to thereby connect the actuating or jarring tool A to thevalve member 15. It should be pointed out that the finder 55 isretracted from its extended position shownin Figure 2 to a retractedposition shown in Figures 5 and 7 when the shear pin 52 is released andthe spring 60 urges the slideable bar or shaft 51 downwardly. Thus, thefinder 55 does not interfere with the'upward movement of the actuatingor jarring tool A after the lock ring 50 has been released and moveddownwardly with respect to the latching arms 42.

With the valve member 15 in the open position and the latch arms 42engaged in the longitudinal slots or recesses 15c of the valve member15, the upper portions or dogs 42b of the latch arms 42 are in the samehorizontal plane as retracting lugs 75 which are mounted in the bore 10aof the housing 10. One retracting lug 75 is provided for each of thelatch arms 42 and the latch lugs 75 age substantially diametricallyopposed with re:

newest spect toeach other and are positioned 90 degrees from the latcharms 42 when the valvemember 15' isin the open position (Figures; 5 and6). 75 are so positioned that their innersurfaces 75a (Figure 6) form acontinuation of the inner surface or bore 10a of the valve housing 10,whereby as the dogs 42b move in a rotational direction relative to thevalve housing 10, they contact the inner surfaces 75a of the retractinglugs 75 and are thereby moved radially or laterally inwardly, which alsoeifects an inward movement; of the lower portions 42a of the latchingarms 42. The lower portions 42a of the latch arms- 42 are retracted asufficient distance to retract same from the; longitudinal slots 150 sothat the actuating tool A is permitted to then drop relative to thevalve member and further rotation of. the valve member 15 is prevented;thus, giving an indication of the completion of the closing of the valvemember 15.

In the operation or use of the valve, construction of this invention,the valve member 15' is positioned in the valve housing 10, which isassembled as shown in Figures 1 and 2, so as to form a continuation or apart of the well; pipe or tubing string 11 from which such assembly issuspended. For purposes of explanation, it is assumed that the valvemember 15 is in. the open position with its ports 21 aligned with theports 20. in the valve housing 10 (Figure 2). The jarring or actuatingtool A is then lowered into the tubing string 11 and passes through. thebore 15a of the valve member 15 a suflicient distance to position thefinder 55 below the annular shoulder 12c of the adapter 12. Then, an.upward movement of the jarring or actuating member A is.effected so thatthe slideable member 51 is held against upward movement and, as a.result, the shear pin '52 is sheared so that the spring 60 urges thelock ring 50 downwardly away from the latch arms 42 and also retractsthe collar finder 55 (Figures 5 and 7) With. the lock ring 50 out oflocked position so that the latch arms 42 are expanded, the upwardmovement of the actuating or jarring tool? A is continued until thelatch arms 42 have been raised above the upper ends 15d of the. valvemember 15,, whereupon the lowering of the actuating or jarring tool Aresults in a guiding of, the latch. arms 42 into the longitudinal,connecting slots 15c of the valve member 15 .to therebyestablish aconnection between the actuating meansA and the valve member 15. Theflexible line supporting the outer sleeve 35 is. then raised. topositionthe pin 37v in the lower portion. of the shaped slot 38, if such pin 37is not already in that position. Then the sleeve35 is permitted to.-fallor drop by slacking the flexible line, and such falling or longitudinalmovement of, the sleeve 35 relativeto the rod 36 eilects a graduallyincreasing rotational movement of the sleeve 35 due to the guiding,action; of the shaped slot 33 moving relative to, the pin 37. Since theslot 38' is preferably gradually increased in. its. inclination, thesleeve 35 has a considerable rotary force as it reaches its lower end ofthe, travel with respect to; the rod: 36, and while such, sleeve- 35.is. rotating, the hammer surface 35a contacts the anvil surface 41a ofthe anvil ring 41 to impart a rotary, jarring: impact-lin a left-hand orcounterclockwise direction (as; viewed from the top. of Figure 1.)- tothe anvil ring 41.. Thus, thesurfaceSSa acts as. a hammer which impartsthe rotary impact to the anvil ring 41 and since the anvil 41 isconnected to'the body 40; and the-body 40 is connected tothe latch arms42; which are engaged in the longitudinal slots 15c, the rotation of theanvil ring 41 effects a turning or rotation of the valve member 1-5. Onelowering of the sleeve 35' withrespect tothe rod 36 is generally insufiicient to turn the valve member 15 from the open to the closed position,so that the sleeve 35' is ordinarily raised and lowered several times inorder to completely move the valve member 15* to its closed position(Figure 7);. Itshould benoted that, as the sleeve 35 islowered rela- Theretracting lugs 6 tive tothe rod 36; the rod 36 isprevented from turningto the right or clockwise by reason of frictional resistance provided bythe contact between the external surface of the valve member 15 and theinternalsurfaceor bore wall of the housing 10, or by anyother-suitable'frictionresistant means. I

As the valve member 1 5- is thusbeing; rotated by the reciprocation ofthe outer'sl'eeve 35" with respect to the rod 36, the cam lugs 25 aremoved from the low points 265 of the cam surfacetoward the high points26ironthe cam ring 26. As the camlugs 25- thuscooperate with the camsurface on the cam ring 26, the-valve member 15 is urged longitudinallyor upwardly E asufiicientamount to tightly wedge the valve member 15 insealing contact with the inner tapered surface 10b of the valve housing10. Also, during such rotation of thevalve member 15, the latch dogs42b-are moved relative to the retracting lugs and, just before the pin33'- contacts the end of the slot 32, the dogs 42b engage the-innersurfaces 75a of the retracting lugs 75 to urge the latch arms 42inwardly and release same from their connected position in thelongitudinal" slots 150. The retracting lugs therefore serve as a stopmeans to 'pr'event further rotation ofthe valve member 15- with the;actuating or jarring tool A illustrated in Figures 17-, but primarilythe retraction of the latch arms 47/ by the lugs 75 serves to indicateatthe surface of the well" when the valve is closed because when the arms42- are retracted', the tool A drops and an increased weight on theflexible support lineis indicatedat the surface of thewell. V

In Figure 8 of the drawings, a modified formof the actuating or jarringtool A is illustrated, and such modified tool is identified by theletterA; Allof theparts of the modified tool' A" are identical withthatillustrated in Figure 1 for the tool A, except that the parts arereversed so that instead of imparting a left-hand or counterclockwiserotational movement (as-viewed from top of Figure 1') to the valvemember'IS as with'the tool A, a right-hand or clockwise rotationalmovement isinrparted withthe modified tool A" so*-that thetool A isadapted" to move the valve element 15 from the closed position to theopen position. The latch arms 42 and the structure for mounting'same atthelower end of the tool A of Figs. 1-7' would obviously'be located atthe lower end of thetool A shownin Fig.7 8. Pref erably, the dogs 42bon. the latch arms 42 'shown in the tool A ofi' Figures 17 are omittedfrom the tool A so that the retracting lugs 75 do not interfere with;the em gagementof the latchingarms 42 in the longitudinal'slots 15's of'the valve member 15'. All parts of the tool" A which are similaroridentical to the parts ofthe tool A have the same identifying numeralsfollowed by a prime mark.

The operation of the modified tool A ofFi'gure 8} is the same as thatshown in Figures '1-7, except that the rotation is in a differentdirection as above explained. Such modified tool A would also besuspended from a cable or-other flexible support and manipulatedthereby.

It should: be pointed out that in the closing of the valve member 15 bythe use of the jarring tool A, the rotation of the valve element 15-with the tool A is limited by the co-action ofi'the retracting lugs 75with the dogs 42b, and by reason of such construction and co-action, thestop pin 33- doesnot contact the extreme left' end" or limit of theslot: 32 (Figure 1). However, inthe event the valve does leak when ithas been moved to the closed position and when thedogs 42b havecontacted the retracting lugs 75* to. retract: the latch arms 42, the'tool A can be removed from. the well tubing or pipe and latch armssimilar to those illustrated. in-Eigure- 8 can besubstituted. forthelatch arms 42 in the tool. A so that the tool. is identical with thatshownin Figure 1. except that the-dogs, 42b, are omitted. With such. a-,construction, the valve element or member 15 can be further moved 7 tothe left or counterclockwise (as viewed from the top of Figure 1). andthe cam lugs 25 will ride up further on the cam surface of the cam ring25 so that a further tightening or wedging of the valve member 15 in thevalve housing is effected' It should also be pointed out that in theopening of the valve by the movement of the valve element or member tothe right or clockwise (as viewed from the top of Figures 1 and 8), thestop or limit of rotation of the valve member 15 is obtained by thecontact of the stop pin 33 with the right end of the slot 32 (Figure 1).

In the usual use of the valve construction of this invention, aplurality of valves are positioned in the Well tubing or pipe and arelongitudinally spaced with respect to each other. In other words, aduplicate valve assembly is positioned above or below the valve assemblyillustrated in the drawings and the valves are both constructed foroperation'or actuation by the jarring tools A and A. With the lockarrangement, including the lock ring 50, for retaining the latch arms 42in the retracted position (Figure 2), the jarring tool A (or A) can belowered through the bore of each of the valves positioned in the wellpipe or tubing. Therefore, the jarring tool can be lowered to aparticular valve which itis desired to actuate or operate, since thejarring tool A or A can be lowered to the predetermined elevation atwhich the particular valve to be actuated is located and then thesequence of operations, as explained above, for their connection andactuation of the jarring tool on the valve element 15 can be effected.

Although various instances wherein it is desirable to selectivelyoperate a plurality of valves in a well pipe will occur to those skilledin the art, the invention is particularly suitable for use in the dualcompletion of oil and gas formations in a well (Fig. 9), wherein onevalve V-l of the type described above in connection with Figs. 1-7 ispositioned above a conventional well packer P and another valve V-2 ofthe same type is positioned below such packer P, with the upper valveV-l being adjacent a gas formation X and the lower valve V-Z beingadjacent an oil formation Y. With such arrangement, the valves can bemanipulated by the manipulation of the actuating tool A of thisinvention so as to open either or both of the valves or the actuatingtool A can be used to close either or both of the valves at the desiredtimes for effecting the various well operations such as washing of themud from the well, acidizing, and the production of the oil through thetubing and the gas through the annulus in the well bore.
